My macbook is often in the "charging" state but is actually not charging, and sometimes I just forget to plug in my charger 🤦 This causes my laptop to run out of battery while I'm playing video games such as Steam or League of Legends 😭

Laptop will say "battery is draining" if the battery is not increasing, and will say "charger is not plugged in" if you didn't plug in your charger.

Done via a long-running script that can be run as a background process.

Assumes you're familiar with opening and running commands in the terminal.

To run as a background process:

nohup ./batteryd.py >/dev/null 2>&1 &

Configs you can set:

❯ ./batteryd.py --help
usage: batteryd.py [-h] [-a APPS] [-s SECONDS_BETWEEN_CHECKS]

optional arguments:
  -h, --help            show this help message and exit
  -a APPS, --apps APPS  only run battery checks when any of these are opened,
                        separate each app with "|". e.g. Steam|LeagueClient
                        (default: None)
  -s SECONDS_BETWEEN_CHECKS, --seconds-between-checks SECONDS_BETWEEN_CHECKS
                        seconds between battery checks (default: 10)

e.g.

nohup ./batteryd.py --apps 'Steam|LeagueClient' --seconds-between-checks 30 >/dev/null 2>&1 &

To check if the background process is running:

ps -ax | grep 'batteryd.py'

To kill the background process:

kill <pid from the ps cmd>

Read code at batteryd.py or can ask me.

• Only works for macOS
• Not friendly for people not familiar with the terminal
  • It's possible create this as a macOS app instead... 🤔
